Product description
Caraway is the mature, dried schizocarpic fruit of a biennial herb of the parsley family (Umbelliferae), native to Eurasia. Each schizocarpic fruit is formed of two caraway seeds and divides into the two half-fruits when mature. These are 3 – 7 mm long, 1.5 – 2 mm wide, crescent-shaped, pointed at both ends, dark brown and have 5 yellowish ridges. The umbels are cut shortly before they reach maturity and dried.
The term spice is used to refer to plant parts which serve to improve the odor and flavor of foods. They contain essential oils and other ingredients which have a strong seasoning action.
Spices are processed, cleaned, graded and carefully packaged for overseas dispatch in the countries where they are cultivated. They are dried to preserve them for transport and storage. In consumer countries, they are delivered to spice mills, where they are cleaned and graded again, ready for sale in unground or ground form.
Spices are classified by the plant parts used:
|
Fruit and seed spices (e.g. pepper, cardamom, caraway) |
|
Bud and flower spices (e.g. cloves) |
|
Bark spices (e.g. cinnamon) |
|
Root spices (ginger, turmeric) |
|
Leaf spices (bay leaf) |
Oil content:
|
5.0 – 7.0% essential oils [1] , in particular carvone and limonene |
|
2.5 – 6.0% essential oils [11] |
|
up to 12% fatty oils [15] |
Quality / Duration of storage
Caraway may be kept for approx. 12 months if the recommended storage conditions are complied with.
Intended use
Caraway is used in the food industry, in medicine and domestically. It is a versatile spice and is used, among other things, for seasoning meat dishes, as a sausage spice, for seasoning vegetable dishes (cabbage dishes), sauces, bread and cheese.

Packaging
Caraway is packaged in jute fabric bags (50 kg), among other things.

Transport
Symbols
 General cargo |
Means of transport
Ship, truck, railroad
Container transport
Standard containers may be used, subject to compliance with lower limits for water content of goods, packaging and container flooring.
Cargo handling
In damp weather (rain, snow), the cargo must be protected from moisture, since this may lead to mold, spoilage and self-heating.
Hooks must not be used in handling bagged goods as they subject the bags to point loads, so damaging them. Due to their shape, plate or bag hooks apply an area load and are thus more suitable for handling bags.
Stowage factor
|
1.75 m3/t (flat bags of jute fabric, 50 kg) [1] |
|
2.69 – 2.78 m3/t (boxes) [1] |
|
1.67 m3/t (bags) [11] |
|
1.70 – 1.81 m3/t (bags) [14] |
Stowage space requirements
Cool, dry, good ventilation
Segregation
Fiber rope, thin fiber nets
Cargo securing
In order to ensure safe transport, the cargo must be stowed and secured in the means of transport in such a manner that it cannot slip or shift during transport. If loss of volume and degradation of quality are to be avoided, the packages must not be damaged by other articles or items of cargo.

Risk factors and loss prevention
RF Temperature
Caraway requires particular temperature, humidity/moisture and possibly ventilation conditions (SC VI) (storage climate conditions).
Favorable travel temperature range: 5 – 25°C [1]
Caraway should be transported in areas which exhibit the lowest temperatures during the voyage and are dry. In any event, storage beneath the weather deck or, in the case of shipping in containers, in the uppermost layer on deck, must be avoided as the deck or container is strongly heated by the intense tropical sun and, at temperatures of > 25°C, essential oils may be lost and there is a risk of self-heating.
Back to beginning
RF Humidity/Moisture
Caraway requires particular temperature, humidity/moisture and possibly ventilation conditions (SC VI) (storage climate conditions).
| Designation | Humidity/water content | Source |
| Relative humidity | 60 – 70% | [1] |
| Water content | up to 14% | [1] |
| maximum 15% | [15] | |
| Maximum equilibrium moisture content | 65% | [1] |
Spices are hygroscopic goods (hygroscopicity), which interact with the moisture in the air. The risk of mold growth is naturally at its greatest in warm, damp air. The cargo may become musty, and the risk of self-heating increases with an elevated air moisture content.
Caraway should be stowed away from goods which are sensitive to moisture/humidity or release moisture (e.g. copra).
In order to prevent condensation on the ship’s side or container walls from affecting the cargo, care should be taken to leave a clear gap between the cargo stack and the ship’s side or container wall.
Back to beginning
RF Ventilation
Caraway requires particular temperature, humidity/moisture and possibly ventilation conditions (SC VI) (storage climate conditions).
If the product is at „shipping dryness“, it does not have to be ventilated during transport. However, if the water content does not meet these guidelines, the following ventilation measures should be implemented to eliminate the potential for dampness:
Recommended ventilation conditions: air exchange rate: 6 changes/hour (airing)
In order to avoid formation of mold, the stowage space should be cool, dry and, most particularly, easy to ventilate.

RF Biotic activity
Caraway displays 3rd order biotic activity.
Caraway belongs to the class of products in which respiration processes are suspended, but in which biochemical, microbial and other decomposition processes still proceed.

RF Gases
No risk.
Back to beginning
RF Self-heating / Spontaneous combustion
An elevated moisture content and excessively high temperatures create a risk of self-heating.
Oil content:
|
5.0 – 7.0% essential oils [1] , in particular carvone and limonene |
|
2.5 – 6.0% essential oils [11] |
|
up to 12% fatty oils [15] |
Back to beginning
RF Odor
| Active behavior | Due to the exudation of essential oils, caraway has a strong, pleasant, intense, spicy aromatic odor and should therefore not be stowed together with odor-sensitive products, e.g. tea or coffee. When transporting spices, it is important to retain the content of essential oils to the greatest possible extent, since these substances, together with other constituents, such as fatty oils, tannins and bitter principles, determine the odor and flavor and thus quality of the spices. The essential oils are readily volatilized and the seasoning action of the spices is consequently reduced. Volatilization of the essential oils is primarily determined by temperature. The higher is the ambient temperature, the more the essential oils are volatilized, as may be recognized by the intense odor in the hold. In the case of caraway, a marked increase in odor may be noted at temperatures of over 25°C. |
| Passive behavior | Caraway is highly odor-sensitive. |
Back to beginning
RF Contamination
| Active behavior | Caraway does not cause contamination. |
| Passive behavior | Caraway is sensitive to dust, dirt, fats and oils. A foreign matter content of at most 5% is admissible, but this should be no more than 0.2% in good quality products [28]. |

RF Mechanical influences
With bagged cargo, point loads applied for example by hooks may result in damage (tears) to the bags and thus in loss of volume. Plate or bag hooks, which, due to their shape, distribute the load and reduce the risk of damage, should thus be used.

RF Toxicity / Hazards to health
No risk.
Back to beginning
RF Shrinkage/Shortage
The natural drying process of the product may cause slight loss of weight.
Back to beginning
RF Insect infestation / Diseases
Caraway consignments may be infested by rats, mice and beetles (in particular drugstore beetles, hump spider beetles, Australian spider beetles and golden spider beetles) and moths (dried fruit and cacao moths) and mites.
